It brings Bluetooth 6.0, true lossless codecs, and a fully differential 24-bit R2R DAC into a single, compact component you can drop into an existing system. Use it with active speakers, a favorite amplifier, or an external DAC. Once it’s in your chain, you can stream freely and hear your library in a new way. Qualcomm Bluetooth and lossless codecs Featuring Qualcomm’s flagship QCC5181 chip, the BR15 R2R supports LDAC, aptX Adaptive, and aptX Lossless. You get up to 2.1Mbps of wireless bandwidth—enough for CD-quality, lossless transmission with stable detail retrieval. Pair your phone or tablet and listen without feeling tied to your chair. LDAC and aptX Lossless for modern listening If your speakers or amplifier don’t support advanced wireless codecs, the BR15 R2R fills that gap. With LDAC and aptX Lossless decoding onboard, streaming video, films, and long listening sessions take on a cleaner, richer character. It brings modern wireless standards to older chains, and gives newer chains room to breathe. Bluetooth 6.0 with extended range Bluetooth 6.0 brings stronger interference resistance, lower latency, and a wider usable range. The external antenna keeps the signal locked even when you’re moving around the room. You can cue tracks from the couch, or from across the space, without dropouts interrupting the moment. Fully differential 24-bit R2R DAC At the center of the BR15 R2R is a proprietary quad-channel, fully-differential R2R DAC. Each channel uses 48 precision thin-film resistors—192 total—with 0.1% accuracy and low temperature drift. The result is a darker noise floor, a smoother background, and the kind of texture R2R fans love. You can run the DAC in NOS or OS mode, depending on the character you prefer. Bluetooth, USB, coaxial, and optical decoding The BR15 R2R fits into all kinds of listening chains. You can switch between Bluetooth, USB, and SPDIF (coaxial/optical) whenever you need. Hook up a phone, a laptop, a CD transport, a television—whatever you use day to day. The device adapts quickly and doesn’t anchor you to one source. Analog and digital outputs for easy pairing Two RCA outputs, one XLR output, and both optical and coaxial digital outputs give you a lot of freedom. Connect to active speakers, feed an external DAC, or run directly into an amplifier. It’s simple to reconfigure as your system changes. Global PEQ and AUTO EQ tools A global 10-band PEQ lets you shape the sound across all modes. Through FIIO’s app, you can load presets or build your own curves. You can simulate or correct the frequency response of your gear, and export or share curves with others. AUTO EQ makes the process even easier—just sync your headphone’s profile and target curve, and let the algorithm handle the fine points. Fully-balanced signal path From the R2R DAC through the low-pass filter and volume control, the entire signal chain is fully-balanced. Noise stays low, distortion remains controlled, and dynamics stay wide. A built-in pop-noise suppression system keeps power-on and power-off transitions quiet. AC/DC dual power supply support Inside, a high-quality switching supply keeps the BR15 R2R stable under normal use. You can also plug in an external 5V DC supply—ideal if you keep a linear power supply on hand. When DC power is connected, the device automatically switches to it, letting you explore different power profiles and sonic characteristics. Custom color display A 1.47-inch LCD screen gives you track information, volume, sampling rate, EQ status, and more. When paired with a compatible Bluetooth source, you’ll also see lyrics. It’s a clean way to check your chain at a glance. Control from near or far Dual knobs and a front display make close-range operation quick and intuitive, especially at a desk. For listening across the room, you can use the included infrared remote or the FIIO Control app to make adjustments without getting up.
